Speaking of channel strips, Would there be a way to patch the "Love Child"into the 528 between the preamp and output section?

It could be done but would require some cleaver routing not allowed for in a normal 500 series rack. You would basically lift the primaries from the first 2623-1 (T2) and "insert" the LC or other EQ there.

Jeff,I really love your aesthetic changes, especially the black pcbs and faceplates! You definitely have offered the whole DIY/recording community with some amazing projects. I hope to jump in on this project soon.

Thanks Brice. I just kinda went in the direction I was pulled in I guess. I really do like the brushed and anodized black too. Plus, the silkscreen shop does a super nice job. I have been thru a few hundred plates since I started using them and have not had one single reject due to the printing.

Hey can anyone help a green DIY guy?I bought the vp28 and somewhere along the way something went wrong. Whenever I plug up the vp28 to my chameleon labs cps-501 I blow the fuse in it. The build was great. I thought I didn't have any problems. I double checked regularly and had a good experience. But soldering and finding the appropriate components from the BOM is the extent of my knowledge. Any suggestions or tests I can run with a multimeter?

Good call! We're on the right path! I have a gar1731 and a gar2520. I took out both and no fuse was blown. I put back in the 1731 in the same location and no fuse was blown. I removed the 1731 and put the 2520 in its original location and blew a fuse. So I guess the problem is the 2520? I'll post some pics. I hope they'll help. If not I hope we can figure it out.

Did only quick tests with a signal generator and an old MD421,but even this was nice to hear on headphones.Will check them next week in the studio,I bet they´re killer!I´ll hook up nice chains then too (VP28s/LC53As/LA500s) in my new 51x racks-very exciting

Easy to build (most time consuming was building the DOAs again),no issues except of 2 left-over parts (guess again ) and 1 splitlock washer which should have been a lock washer from what I understood.Oh,and the shrink tubes for the I/P signal present leds are too long........

Again:Thank you very much for this nice and great sounding gear Jeff,another very well done project indeed-CHAPEAU BAS!

Cool you got it sorted.I wanted to say that some of the parts seem to be a bit far off from the pcb surface.Beware of shorting things out by touching each other,the area around R14 to R8 as well as the resistor and the diode arrangement D1A-B seem to be very close to contact in your picture.

I measured the current,loaded with gar2520s,boosting a -50dB signal to around unity gain.Results are 59mAs on positive and 55mAs on negative rail.Given around 60mAs on both one can drive more than 20 pres from a single 51x psu,without even touching the 24v rails,cool!Sadly I can not measure the inrush current......

So I did some first tests with speech (narrator) and a male singer in our studios.I used an U87Ai (like most of the times).The vp28 has always a nice character,but you can get tons of sounds from it!What a great preamp!It is never "clinical" sounding,always nice to dial in using both the gain and fader pots,a lot of variations can be achieved easily.The filters work great and give a supercool control over the subs you want to remove or just flatten a bit.After that I hooked up a channel strip using the modules as shown in the picture in my previous post (vp28-lc53a-la500).People-this strip is a KILLER!!!I prefer it over a m*n**y v*xb*x,no joke!

I just finished my first VP28 and without Chunger's documentation finished! Slowly recovering from my first assembly (and failure) with a 7-0 win streak!

Almost fried my monitors (and ears) when i pushed the MIC button with all knobs at full gain, but hey, you learn from experience xD

If i hear my voice that means i assembled both GAR1731's correctly and nothing's wrong? (it surprises me a little, plus im so bad with a DMM that every pre i finished goes directly in the lunchbox, testing is for noobs......)
